The author concludes his memoir with the following aphoristic 

 summary : — 



1. First of all it is to be determined what plants are to be 

 cultivated in a given Plant-house, or its separate parts. The 

 more select the choice, the more judicious their grouping ac- 

 cording to habits and culture, the easier and cheaper will be the 

 execution of the structure, and the treatment of its contents. 



2. The distinction between a Serre d' exhibition, "ein hohes 

 Schauhaus " (large stove conservatory ?) and a low stove, " eiu 

 niedrigeres Gewachshaus," must be kept rigidly in view, accord- 

 ing to their different requirements ; and it is preferable, 

 accordingly, as regards economy and management, to have two 

 separate buildings, instead of one, for accomplisliing the objects 

 in contemplation. Plants of low and humble growth should be 

 banished from a large building destined chiefly for trees and tall 

 shrubs, and placed in one of suitable elevation. 



3. In the construction of a Stove-Conservatory, it is an impor- 

 tant consideration, whether the intention is to exhibit the growth 

 and habit of its inmates, or chiefly their flowers and fruits. 



4. In order to favour, in the greatest degree possible, the har- 

 monious growth of the plants, to obtain a uniform development of 

 branches and leaves, such a building must be capable of admitting 

 light from all sides, 



5. But this object may be attained in our climate, by admitting 

 light to the North, from above, independent of its indispensable 

 access from the South, and also the East and West; for reflected 

 light acts more powerfully than direct, in proportion as the angle 

 of incidence of its rays is greater. 



6. If it is found desirable to apply glass extensively on the 

 north-side, this important result will be attained, that it will con- 

 tribute towards maintaining as uniform a degree of heat within as 

 possible (by preventing its accumulation in the higher strata of 

 air), and promoting transversal currents. 



7. In both the one and the other description of buildings, it is 

 particularly to be attended to, that shade-plants are kept entirely 

 apart from others ; if in the same house, they require distinct 

 treatment. 



8. The plants which belong to the Stove-Conservatory are 

 those peculiar to the forest vegetation, both the loftiest and ordi- 

 nary, of their native country ; and as the denseness of a forest
